Trunk comparison: Kia Ceed vs Seat Tarraco

Key Differences
The SEAT Tarraco offers significantly more cargo length: with the seats folded down, it is 13 in (21%) longer than the Kia Ceed and with the first row of seats upright, also 13 in (42%) more. The trunk opening of the Tarraco is 3.1 in (11%) higher, and the opening width is 5.9 in (15%) wider compared to the Ceed.
The loading edge of the Tarraco is 3.5 in (14%) higher above the ground. In contrast, the Kia Ceed has a greater depth from the loading edge to the trunk floor: +2 in (83%). The narrowest point in the trunk is only slightly wider in the Ceed: +0.8 in (2%), which is hardly relevant.
Impact on Usability
Due to the longer loading area and the wider and higher opening, the Tarraco is better suited for long or bulky items (e.g., furniture parts, long boxes, skis) and for loading bags or bulky luggage with the seats folded down.
The higher opening facilitates loading tall items through. However, the higher loading edge makes lifting heavy loads more strenuous.
The Ceed scores with a greater depth between the loading edge and the trunk floor and a lower loading edge, which makes loading heavy luggage or boxes ergonomically more favorable and facilitates vertical stacking. Due to the shorter length and narrower opening, it is less practical for very long or wide loads.
Conclusion: Those who frequently transport long or wide items benefit from the Tarraco (more length, wider/higher opening). Those who often lift heavy, bulky luggage and need to stack vertically have everyday advantages with the Ceed (deeper loading area, lower loading edge).
